Answer 1

Answer:

Formula- NaHCO3

Preparation of Baking soda:

Solvay process is used for the production of sodium bicarbonate and sodium carbonate industrially. In this process carbon dioxide, water, ammonia and brine solution in its concentrated form, are used as raw materials. This process is used mainly as it is inexpensive and less number of raw materials is used to produce necessary chemicals. The important chemical reaction that is used in the production of baking soda and sodium carbonate is:

The following reaction takes place when it is heated during cooking:

2NaHCO3 -- Na2CO3 +H2O + CO2
